# ./blender -b test.blend -P demo.py
# -b = background mode
# -P = run a Python script within the context of the project file

# Init all of the variables needed by this script.  Because Blender executes
# this script, OpenShot will inject a dictionary of the required parameters
# before this script is executed.
